READING CODES PO340 AND PO300

1998 Suzuki Sidekick • 15,300 miles

98 sidekick automatic 4x4 idle surges up and down when cold and levels off to a stall out after warm and runs rough and can not drive or it wont go fast enough.I replaced o2 sensors as it needed them for a good while, than the maf and after that a few days it started rough idle, my cat was not even a year old. Now I hear a rattle sound in it like something is bounceing around in it. When I rev the motor it revs good just wont idle right and in drive has no pick up just boggs. Thanks for any help you can spare. Mj

Thank you, Now on the trouble tree you sent it says the harness plug I assume the plug on pcm? It says the it has 26 pin, my bplug on pcm is only 7, am I at the right plug?There is no other plug on pcm.

Sounds like you found something other then the pcm I posted a diagram of where it is its number 22 in the diagram.I dont have a access to the connector faces and pin outs on the vechile. You would just find the connector thats 26 pin and the other one which they say is 22 pin and count from the end the amount of pin numbers they say which is 3. The wire should be white if you started from the correct end. Let me know what you find.

Well some how were not on same page here, the trouble tree said nothing about being under the dash for anything, It only said to remove pcm and turn it to test it once the testing plug is found, which in fact led me to believe it was in general area under hood, is that last diagram wireing under hood? If so its not very clear, I cannot even blow it up like I could the trouble tree.

The pcm is under the left side of the dash according to my info. It may seem like it to you its under the hood from the trouble it is not under there.

Here is what I found; 2.51 v constant, never drops to 0 with rotation. No short to grn on this white wire.

Are you talking about the step 2?If so if the voltage is constant you go step 4 which says check for a open in the wire which ever color yours is of no open replace cam sensor.

Can the cam sensor be replaced by its self? Or do I have to replace whole distributor?
